Manipulate inbound route at a trunk level

AnthKay92 · July 24, 2019, 1:16pm

Hi,

I have set an inbound route of +390744087128, which goes to extension 1001. When the call comes in as +390744087128 it matches the inbound route and goes to extension 1001 as expected.

When the call comes in as 00744087128 there is not a matching inbound route to send the call (it works for example when I add an additional inbound route of 00744087128 to extension 1001)

Instead of having multiple inbound routes, I would like to manipulate the call as it comes in, so add +39 and strip one 0…

On my trunk I have tried the following:

The call is still being presented inbound as 00744087128 as you can see in the SIP trace.

Is there a way I can manipulate this permanently rather than have 2 different inbound routes??

Thanks in advance for any help!

Prefix will strip, prepend will add.

AnthKay92 · July 24, 2019, 1:22pm

We have tried with Prefix 0 and Prepend of +39
The call still comes in as 00744087128

AnthKay92 · July 24, 2019, 1:25pm

So in theory 00744087128 should then be +39744087128
It’s still 00744087128 as per the logs above

comtech · July 24, 2019, 1:26pm

I did not see it on you’re example. Is it the first pattern? The fist matching pattern is what will be used.

lgaetz · July 24, 2019, 2:05pm

The trunk dial rules in the GUI are only for outbound calls. To normalize CID/DID on inbound calls requires a block of custom code. There are several threads here describing how people have done this. This is not exactly what you need, but the basics are here: DID from provider breaks incoming routes (DID matching)

AnthKay92 · July 24, 2019, 2:14pm

Thanks Lorne, my only problem here is that I am already using the from-pstn-toheader context to allow for the +39 to be accepted in the system…

Is there any way I can use this along with a custom one?

Thanks

lgaetz · July 24, 2019, 2:18pm

You would have to incorporate the dialplan from from-pstn-toheader into your custom dialplan.

AnthKay92 · July 24, 2019, 2:30pm

So I would create a new context named from-pstn-toheader-custom and point my trunk to this…

Add the below:
[from-pstn-toheader-custom]
exten => _.,1,NoOp(Attempting to extract DID from SIP To header)
exten => _.,n,gotoif($[“${CHANNEL(channeltype)}”=“SIP”]?SIP)
exten => _.,n,gotoif($[“${CHANNEL(channeltype)}”=“PJSIP”]?PJSIP)
exten => _.,n,NoOp(Unable to determine SIP channel type)
exten => _.,n,goto(from-pstn,${EXTEN},1))
exten => _.,n(SIP),Goto(from-pstn,${CUT(CUT(SIP_HEADER(To),@,1),:,2)},1)
exten => _.,n(PJSIP),Goto(from-pstn,${CUT(CUT(PJSIP_HEADER(read,To),@,1),:,2)},1)

But then not sure how I will format to remove 00 and add +39… any ideas?

Thanks for all your help

AnthKay92 · July 24, 2019, 2:33pm

More so that normal inbound numbers match to the inbound route and then any different formatting take the context as above, not sure how I would apply this in a custom context.

cynjut · July 24, 2019, 3:00pm

There’s another context that does that:

Take the one you wrote above and add code like the e164 context to chop up the CID.
